An apparatus () serves for linear illumination of a moving product web (), the apparatus () having at least one light source () emitting light. In order to achieve high luminance in a linear subregion of the product web (), at least a portion of the light emitted by the light source () is reflected towards the product web () by at least one tubular reflector (). The tubular reflector () in this case has at least one light exit slit () which is assigned to the product web (). Moreover, the tubular reflector has at least one observation slit () which lies opposite the light exit slit (). The illuminated product web () can be observed through this observation slit () by means of a line camera ().

A battery pack () for an associated hand-held electric machine tool () and for an associated charging device () including an analog temperature sensor () with a negative temperature coefficient and a temperature measuring interface () accessible from the outside. Battery protection electronics () arranged in the hand-held electric machine tool () and in the charging device (), which have a battery protection logic () and a power switch () that is arranged in the circuit path () of the battery pack () can be influenced. The battery pack () is provided with an emergency protection circuit (), which is connected in parallel with the analog temperature sensor () and which, in emergency situations, can actively reduce the total resistance (R) measurable from the outside via the temperature measuring interface ().
